Debian Configuration :: Multiple Network Interfaces With VirtualBox?
Mar 29, 2010
I have a rather urgent problem with my network, I got two virtual network interfaces one internal and one external. The problem is; I can't get connection to internet. The external NIC is set as a NAT and the internal is... internal.
/etc/network/interfaces
auto eth1
iface eth1 inet static
address 192.168.1.200
netmask 255.255.255.0
Running with this configuration makes my internet connect go away, however if I remove the configuration for eth1 everything is working fine.

I had one of those random system deaths, so reinstalled squeeze (daily netinst image I think...) on my eee 1000, which uses an rt2860 wireless chip. The new install only installed 2.6.32, which I had been avoiding using because of a few problems, including it dealing with networking slightly differently. I couldn't get it to work - even without encryption - using wicd. Having had a read of [URL]... , I had a look at /etc/network/interfaces, which read; This file describes the network interfaces available on your system and how to activate them. For more information, see interfaces(5).
[code]...
ra0 is now called wlan0, as far as I'm aware. I've read in several places that it is best to expunge this file of all references to wifi, so I removed the bottom section (after '# The primary network interface'). I still got nothing. However, if I go ahead and change the 'ra0's to 'wlan0's, it seems to work - wicd connects. Not very familiar with Debian (spent more time on SUSE. Drop your tomatoes - I like it. Any idea what is happening? Is what I'm doing wrong? Conversely, is the file wrong? Should it be reported? Against which package? Including any particular files?

I have a netgear wg111t that is running with ndiswrapper. It has an atheros chipset, but calling it ath0 didn't work.
Heres /etc/network/interface :
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface auto lo
iface lo inet loopback

I was just wondering if there's any point having both auto and allow-hotplug against the same interface in network/interfaces as allow-hotplug seems to bring an interface up at boot on its own.

I have a Dell PowerEdge SC430, Squeeze 6.0.2 box, Broadcom NetXtreme NIC which works fine DHCP. The network-manager package is not installed. I have now reconfigured /etc/network/interfaces for a static IP:
auto eth0
iface eth0 inet static
address 192.168.1.2

What is the maximum number of virtual network interfaces possible?I would like to create around 300 or so. This is needed to simulate a 300 node network.

Alright, every time I boot or shutdown my routing box, it hangs at configuring and deconfiguring network interfaces. Below is my interfaces file. I see no errors or warnings in my log and I am running a pure kernel, not tainted with proprietary drivers. All of my hardware is 100% supported.

As above, my wheezy 32bit hangs at boot. the last few lines displayed are
Code: Select allMounting local filesystems...done.

I removed the files from /etc/network/interfaces.d/ just in case. i still can't boot up.

i recently started sockets programming. In the process i began to look for relevant network information about my computer and realized that ifconfig wasn't displaying the same information that resides in my /etc/network/interfaces file. On the interfaces file my IP address is 192.168.1.109 for interface eth0 but ifconfig displays 192.168.1.101. I was under the impression that ifconfig got its information from the interfaces file but clearly doesn't. I tried re configuring the device with ifconfig and then disabling and re enabling the device with ifdown and ifup so that the device updated its information but it didn't.

I need to set up a little virtual network with Debian Lenny guests (the host is Debian Squeeze, but I don't think it matters). I installed Lenny in a VM and it works fine. Then I cloned the hard drive, garion@Laptop:~$ VBoxManage clonevdi Linux 1.vdi Linux 2.vdi created a new VM with exactly the same settings as the first one and booted the new disc. The problem is that there's no eth0 in the new VM, but it is in the original one. Also if I "unplug" the cable, dmesg won't notice anything. In the original VM it works fine. They both have the same virtual network card: PCnet-FAST III (Am79C973). I've also tried NAT as well as internal network settings.

I have a problem where multiple interfaces in my network manager have the same name. This means that I am unable to have different settings for each interface. Here is my setup:
Ubuntu 10.04 LTS
uname -a: Linux muon 2.6.32-30-generic #59-Ubuntu SMP Tue Mar 1 21:30:21 UTC 2011 i686 GNU/Linux
Adapter 1: 02:00.0 Ethernet controller: Intel Corporation 82573E Gigabit Ethernet Controller (Copper) (rev 03)
Adapter 2: HTC Desire tethered via USB. When I start from scratch, with no remembered networks in the network manager, the Ethernet is shown as "Auto Ethernet". When I then connect the HTC Desire, the new network is shown in the network manager also as "Auto Ethernet". Previously, when I right clicked on the network manager and selected "Edit Connections", there were multiple "Auto Ethernet" entries under the wired tab.
Now (and I do not know what changed, sorry), I only see one entry. When I edit this entry (say, add a route), then the route is added for both network interfaces. This used to still work, so I was not worried about the name clash, but now it is causing problems so I need to have a different name for each network interface.

configure a server with two network interfaces? This system is physically moved from one network to another every few days (different buildings but connected by a VPN). I'd like to be able to control the IP address of the system depending on which port I plug the network cable into with a static setting. Right now the system will connect to the local network, but any requests to go beyond the subnet get lost. The only way I can get the system to talk outside of its subnet is to comment out the second interface.
/etc/network/interfaces:
auto lo
iface lo inet loopback
auto eth0

Similar to the linux command "chattr +i filename", I would sure like to set my eth0 interface immutable. so once I assign the eth0 interface's IP and gateway, make it stay set until I say otherwise.
this way, I can run dhclient or Networkmanager on another interface without having to fret that it may alter this interface. is there something out there that can do this?

I have a laptop connected to internet via wlan0. I also have eth0 interface and with it I share internet. I want to modify/filter all the traffic passing by the first laptop, something like this:
Code: Select all          *---------------------------*
          |    LAPTOP 1      |   *--------------* ?
          |-----*  *------*  *----*   |       |
  INTERNET<------>|wlan0|<-->|MY_APP|<-->|eth0|<---->|ANOTHER LAPTOP|
          |-----*  *------*  *----|   |       |
          *---------------------------*   *--------------*
I know that in FreeBSD it is possible to use ipfw for that purpose, because it build-in into kernel. We set for example rule Code: Select allipfw add divert 2000 ip from any to 1.0.1.1
and we can use our own application to process those packets, reinject them forward etc. It will work also fast, because as I said, it build into kernel.
Is there any standart Linux-based solution to do the same? I found some info about netmap-ipfw. Is this a correct solution? Or I have to use for example IP-aliases and iptables to do that?
I need to process all the IP-packets, not only TCP/UDP/etc-protocol. Solution also must be very fast.

My new Squeeze machine detects all of my hardware including the LAN and WLAN cards, but only brings up the LAN card. There isn't even an entry for it in /etc/network/interfaces for me to modify. I tried adding the info manually but then the entire network wouldn't start. I had it configured as a static IP and I know the commands were correct due to them working on the LAN card. I believe that the name "wlan0" was causing the problem, but how else can I bring it up at boot?

I'm trying to connect one computer to two others in an ad-hoc infrastructure.
[computer 1] ---- [computer 2] ---- [computer 3]
computer 2 is running Linux and has a single NIC wlan0. I want to it to connect to both computer 1 and computer 3 so each computer can talk to the other. No switch is available so it needs to be an ad-hoc setup.

If I try to add a new interface (eth1) to /etc/network/interfaces, I get
Code:
* Reconfiguring network interfaces... SIOCSIFADDR: No such device
eth1: ERROR while getting interface flags: No such device
SIOCSIFNETMASK: No such device
[Code]...
How do I add 2 interfaces and get anyone of them to work, as available ?

So I've always asked this in the past when I get on a Debian system. This makes no sense to me but I just don't see how I restart network interfaces (i.e. eth0) on a standard Debian install. If I change the static I.P. address listed in /etc/network/interfaces from x.x.x.100 to x.x.x.101, I then assume I can simply do any of the following:
- /etc/init.d/networking stop | start
- ifdown eth0
- ifup eth0
- service networking stop
- service networking start
All the commands above do nothing. My only solution I know that works and implements the changes I've made is a complete system reboot which to me in Linux, is ridiculous. I've struggled with this over and over and nothing I do correctly assigns the new I.P. in the 'interfaces' file to the actual adapter. This isn't my single isolated Debian machine but every Debian machine I can get my hands on. Servers, workstations, VM's, any release, etc etc etc. Below is my interfaces configuration file:
Code:
auto lo
iface lo inet loopback

How do Linux identify the eth0, eth1, eth2 interfaces. For instance I plug in a network cable in to an interface. How do Linux recognize the plug in interface is eth0 or eth1?

I had some trouble with the netinst CD and I had to install lenny with the 6DVDs instead. My internet connection only works after I edit the interfaces and resolv.conf files manually. So my question is: can I do that from the netinst CD before it actually needs the connection to install everything? (otherwise I'll just need to use the DVDs.

I recently installed debian testing, amd64, on my box and I am running the xfce desktop. When I login, I always get a bubble popup telling me that virtualbox is not running. Is it something I should be worried about? I use only Linux on my machine.

I've installed newest Debian (Squeeze) and then on fresh system made instalation of VirtualBox OSE as it is written on http://wiki.debian.org/VirtualBox.
I've also created virtual machine, however when I try to run it I got error message:
RTR3Init failed with rc=-1912(rc=-1912)
Please install the virtual-ose-dkms package and execute 'modprobe vboxdrv' as root
And later on code...

I have installed installed Debian 9 (stretch/unstable) which has GNOME 3.16.3 and runs Linux kernel 4.1.0-2 by default in Virtualbox 5.0. The host OS is Windows 8.1 On each instance of activating full screen mode in the VM, a freeze occurs then an abrupt close (abort).
I am inclined to believe that this problem resides in the OS (Debian 9) rather than Virtualbox or the Host. The reason being is that prior to installing Debian 9 (today) I had Jessie installed for quite some time where this error/issue never surfaced.
This issue is rather complicated in the sense that if alternating between full screen and normal mode quickly, this occurs whereas, if done every 10 seconds or thereabout it happens almost seamlessly. Also, if 3DAcceleration is switched off that doesn't occur.
How do I find the root of this problem and a resolution to it?

I have installed the latest virtualbox 4.1 on my desktop and laptop. It hosed suspend and hibernate.
The laptop is A Dell D630 with Intel Core2 Duo CPU, the desktop is an AMD based ASUS M3N78-VM mobo with Athlon II x2 250 CPU. Debian Testing 32-bit (same results with the 2.6.39 and the 3.0 kernels). Both have nvidia cards though - the desktop an integrated 8200, the laptop a NVS 135M. But suspend/hibernate was working before with the 4.0 series virtualbox.
The workaround is to clear the vboxpci vboxnetadp vboxnetflt vboxdrv modules from the memory before suspend/hibernate. I added the
service vboxdrv stop
rmmod vboxpci vboxnetadp vboxnetflt vboxdrv
lines to my sleep script (i dont use power managers, just the acpi powerbutton/lid scripts modified). Everything is ok now.
